[0033] In some embodiments, the operation method of the neodymium iron boron blank unpacking transfer mechanism of the present application is as follows:

[0034] First, a protective film is wrapped around the formed blank material, and then the blank material is loaded into a special vacuum bag to achieve an oxygen-free process of the product;

[0035] The blank material loaded into the vacuum bag is placed in a special isostatic pressing transfer cylinder 1 and isostatic pressing is started. After isostatic pressing is completed, the isostatically pressed blank material is directly placed in the special isostatic pressing transfer cylinder 1, and the isostatic pressing transfer cylinder 1 is transferred to the vicinity of the transfer box 2. Then, the isostatic pressing transfer cylinder 1 is hoisted by a crown block to the transfer box 2, the transfer sealing cover 201 of the transfer box 2 is closed, and oxygen is discharged. This not only greatly saves the labor intensity, but also reduces the problem of corner dropping of the blank caused by manual errors after isostatic pressing.

[0036] After the oxygen in the transfer box 2 is exhausted, the lifter 202 at the bottom of the transfer box 2 starts to work, and the staff starts to remove the special vacuum bag (at this time, the protective film of the blank is not torn off yet), and then is placed on the transfer table 308 of the special blank transfer trolley 3, at this time, the oil molecules in the transfer box 2 will adhere to the protective film, which can ensure that it will not penetrate into the blank, and the blank in the transfer box 2 is removed in turn; the transfer box 2 is generally provided with two, one is used for exhausting oxygen, and the other is used for docking with the transfer sealing box 306; when the lifter 202 lifts the transfer cylinder 1, the transfer sealing cover 201 is opened, and at the same time, the transfer sealing cover 3061 of the transfer sealing box 306 is also opened, the transfer cylinder 1 enters the transfer sealing box 306, and after the operation is completed, the lifter 202 is recovered, and the transfer sealing cover 201 and the transfer sealing cover 3061 are closed at the same time, and at the same time, the other transfer box 2 is exhausted, and the transfer box 2 moves to the transfer sealing box 306 and is docked with the transfer sealing box 306, and the above-mentioned operation is continued. The setting of the double transfer box 2 can greatly improve the work efficiency.

[0037] After the vacuum bag is completely removed, and the belt is removed into the furnace trolley to reach below 80PPM, the transfer trolley 3 starts to move at a constant speed in a specified direction through a moving speed reducer and a driving wheel 303, and is ready to be docked with the bag removal furnace trolley 4;

[0038] After the front door docking gate 304 of the transfer trolley 3 is docked with the rear door docking gate 401 of the bag removal furnace trolley 4 and is opened, the transfer table 308 of the transfer trolley 3 is transferred into the bag removal furnace trolley 4 through a lead screw transmission of a positioning linear guide rail 302 (at this time, the oxygen content in the bag removal furnace trolley 4 is below 80PPM), the lead screw is retracted, at this time, the front door docking gate 304 and the rear door docking gate 401 are closed, the staff starts to remove the protective film on the blank in the bag removal furnace trolley 4, and places the blank in the graphite box special for the sintering furnace; and

[0039] After the protective film is completely removed, the elevator carrying the graphite box is lifted to a specified height and starts to be docked with the sintering furnace.

[0040] In summary, the Nd-Fe-B blank bag removal transfer mechanism has the following advantages: the scheme is changed from the original isostatic pressing to be directly hoisted into a special small trolley, which greatly reduces the labor intensity of workers and also reduces the problem of corner dropping caused by manual operation; the problem that the oil molecules in the box body adhere to the surface of the blank due to long-time work, causing the increase of the carbon content of the surface skin and affecting the performance of the product is overcome; the scheme first removes the vacuum bag through the transfer box, then removes the protective film in the bag removal furnace trolley, and then enters the sintering furnace, which can ensure that the Nd-Fe-B magnetic material is not in contact with oil, thereby further improving the coercive force of the product.
